Good afternoon, I've been trying to configure the network for several days, I have read all the posts and tried multiple configurations, some even KO the server like this https://forum.proxmox.com/threads/proxmox-network-config-on-hetzner .36245 / page-2 # post-380458, I have read the official proxmox admin guide along with the one offered by Hetzner there is no way to give internet to my VMs, I currently have a VM with W10, one of the last tests is with Private IP subnet and using tablet IP as indicated and neither, I have PVE 6.3, what am I doing wrong? In the post indicated above, which says it works, the physical server is unavailable, I had to go into rescue mode and load old conf. Greetings and thanks for your help.
[SOLVED] Proxmox and Hetzner Impossible to configure

Have you tried it without blank lines before the `post-up` lines? They should be right after the interfaces they belong to without a blank line AFAIU.
Why is this commented out? For routing to work, IP forwarding needs to be enabled.
Hello, I was doing tests, that's why I was commenting, it already works for me, it was because of the separation of the MAC-IP that Hetzner does, I have deactivated it and it already works, peljl has also helped me. Thank you very much, now I am still testing to combine bridge and router mode. Greetings
